Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Assessing the Mechanism of NH3 Sensing in Flexible Carbon‐Nanotube‐Based Chemoresistive Sensors via In Situ Photoemission Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Flexible carbon nanotube chemoresistors detect NH3 through charge‐transfer interactions directly revealed by in situ synchrotron X‐ray photoelectron spectroscopy. Binding‐energy shifts of ≈1 eV correlate with resistance changes, demonstrating that intra‐CNT charge transfer between NH3 and CNTs is the dominant sensing mechanism.

Volatility and the role of order book structure [PDF]

open access: yes
There is much literature that deals with modeling and forecasting asset return volatility. However, much of this research does not attempt to explain variations in the level of volatility.

Eco‐Friendly Schiff Base Cellulosic Adsorbent for Selective Removal of Cationic Dyes from Petroleum Wastewater: Synthesis, Characterization, and Application

open access: yesAdvanced Materials Interfaces, EarlyView.
The porous HMC selectively captures cationic dyes (MB and MG) from contaminated water, transforming dark, dye‐laden effluent into clean water. ABSTRACT Our investigation explores the exclusion of two health‐risk cationic dyes (e.g., Methylene Blue (MB) and Malachite Green (MG)) using a novel hydrazone‐modified cellulose (HMC) adsorbent synthesized via ...

Functionalized Anti‐Cryptophane‐A as a Platform for Type II Porous Ionic Liquids

open access: yesAdvanced Materials Interfaces, EarlyView.
Type II porous ionic liquids were prepared at room temperature by dissolving alkyl‐ and fluoroalkyl‐functionalized anti‐cryptophane‐A cages in phosphonium‐ and pyrrolidinium‐based ionic liquids. Molecular‐level evidence demonstrates that the cages retain permanent internal porosity in the liquid state, leading to up to an elevenfold enhancement in ...

Forecasting the conditional volatility of oil spot and futures prices with structural breaks and long memory models [PDF]

open access: yes
This paper investigates whether structural breaks and long memory are relevant features in modeling and forecasting the conditional volatility of oil spot and futures prices using three GARCH-type models, i.e., linear GARCH, GARCH with structural breaks ...
